The opinion of the court was delivered by: Morrison C. England, Jr. United States District Judge
The Court is in receipt of the Notice of Supplemental Authority (ECF No. 59) filed Thursday, May 24, 2012, by Defendant-Intervenor Natural Resources Defense Council, Inc. ("NRDC"). NRDC submitted for the Court's review the decision of the United States Environmental Protection Agency ("EPA") approving California's inclusion of the Regulation to Reduce Emissions of Diesel Particulate Matter, Oxides of Nitrogen and Other Criteria Pollutants, from In-Use Heavy-Duty Diesel-Fueled Vehicles ("Truck and Bus Regulation"), 13 Cal. Code Reg. § 2025, within its State Implementation Plan ("SIP").
See Final Rule, Approval and Promulgation of Implementation Plans, 77 Fed. Reg. 20308-01 (April 4, 2012) (to be codified at 40 C.F.R. pt. 52). At the time the parties filed their papers, the EPA decision was still pending. Now that an agency decision has been rendered, the Court deems it necessary to order further briefing regarding what effect the EPA's above approval will have on the parties' positions in this case. See, e.g., Association of American Railroads v. South Coast Air Quality Management Dist., 622 F.2d 1094, 1098 (9th Cir. 2010) ("Once approved by EPA, state implementation plans have the force and effect of federal law.")
